Abstract: Abstract of the Disclosure The invention relates to a thermostatic control unit for radiator valves, this unit being of the type which has an adjustable bellows.  The bellows is adjusted only during initial calibration of the thermostatic control unit or when the temperature setting of the unit is changed.          The control unit includes a screw and nut arrangement in which the nut is attached to the free or moving end of the adjustment bellows.  About three turns between the screw and the nut have been found suitable to provide a sufficient movement of the nut to allow an adequate adjustment of the bellows.  A problem with prior units of this type is that if the screw is turned inwardly more than three turns the thread may bottom and thereby cause an excessive and damaging torque to be transmitted to the bellows.  Alternately, if the screw is turned outwardly to disengage from the nut, the nut becomes cocked in the enclosed casing and it becomes impossible for the screw to re-enter the nut.  The above disadvantages resulting from an excessive turning of the screw in either direction has been overcome by the present invention by providing a construction which positively limits the turning of the screw to about two revolutions.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to an oil recovery string and oil extraction process for use in the recovery of oil from natural oil-bearing formations, in particular unconsolidated tar sands, with improved efficiency and lower installation and operating costs.  The invention utilizes an oil recovery pipe with dis-tribution of heat into the formation from the pipe.  One impor-tant discovery underlying the invention is that when employing thermal energy to cause flow of oil within an oil-bearing forma-tion into a collecting pipe, important advantages are achieved if heat is released into the formation at the site of the col-lecting pipe.  In particular, favourable oil recovery rates can be more quickly achieved and long term recovery rates can be improved.  By providing an oil recovery string which serves both for oil collection and for heat distribution, the present inven-tion enables these advantages to be realized and in addition makes an important contribution to reduction of costs by reducing the number of drilling or string driving operations required.          The invention therefore comprises an oil recovery string for use in recovering oil from a natural oil-bearing formation with the aid of thermal energy supplied by a fluid heating medium, said string comprising a tubular casing within which there is at least one internal passageway along which heated fluid medium for supplying thermal energy to a said formation can be passed, and at least one duct along which oil can flow along the string, said casing having oil entry apertures disposed at intervals therealong, which aper-tures are in communication with the interior of said duct.

Abstract: TITLE OF THE INVENTION:            APPARATUS FOR AUTOMATICALLY FEEDING INDIVIDUAL SHEETS          FROM A STACK THROUGH AN OFFICE MACHINE         ABSTRACT OF THE DISCLOSURE:     This apparatus removes individual sheets of paper or the like from a stack regardless of the thickness of each sheet.  A sheet supply stack support is journaled in a housing in   see-saw fashion.  A first set of sheet separating rollers is ar-ranged above the downstream end of the support as viewed in the direction of sheet movement.  A spring urges the downstream end of the support upwardly and thus sheets on the support against the first set of rollers.  A table is located substan-tially adjacent said downstream end and below a second set of sheet separating rollers.  The table has a cut-out and a sheet separating gate slants through the cut-out below the second set of rollers.  The gate is spring biased toward the second set of rollers. Two sheet guides are arranged upstream and downstream, for example, of a platen.  The supply stack is arranged upstream of the first sheet guide.  The sheet receiving stack is arranged downstream of the second sheet guide and substantially above the sheet supply stack.  Both stacks are arranged in relatively flat positions to the horizontal.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus is disclosed for manufacturing a nonwoven fabric having alternating stripes of high fiber density and low fiber density with substantially all of the fibers in the stripes of high fiber density oriented in substantially one direction, for example the machine direction, and substantially all of the fibers in the adjacent stripes of low fiber density oriented in a direction substantially normal to that direction.  This phenomenon can be produced by a fluid propelling means for carry-ing discretely separated fibers in a fluid-borne stream, and a set of finger-like striping bars that are disposed, equidistantly from each other, directly over a moving conveyor screen or by a set of impervious resist areas in the shape of bars, or the like, disposed directly on the moving screen.  As the fluid-borne stream passes onto the section having the striping bars or resist areas, a majority of the fibers in the stream are attracted to the spaces between the bars and are generally disposed in an orientation that follows the direction of the striping bars, while a lesser number of fibers are disposed across the bars and remain in a generally cross direction to those bars after the thusly formed web of fibers moves entirely onto the moving conveyor screen.  Some of the fibers in the fabric may advantageously be of a thermo-plastic nature so that when heated, they will provide a binder for the fabric.

Abstract: ABSTRACT OF THE DISCLOSURE     A tandem rack dishwashing machine in which the single unit model is designed to handle two half-racks at a time and arranged in tandem, the half-racks supporting soiled dishes, or one full rack at a time; and in which the double unit model is designed to handle two full racks of soiled dishes at a time and arranged in tandem, the double unit model having a control switch in series with a starting switch and positioned at the exit end of the machine so as to be closed by the racks only when the two full racks are received within the washing and rinsing area.  The dish-rinsing water need not be at 180°F., because the rinse water is chemically sanitized and need be only at 140°F., which is the same temperature as the wash water.  Novel means is used for quickly draining the wash water from the machine into a holding tank which then feeds it into the sewer.  This reduces the time required between the draining of the wash water and the filling of the machine tank with the required amount of rinse water and thereby reduces the time required for the complete washing, rinsing and sterilizing of the dishes.

Granted: 1980-05-06
Abstract: ABSTRACT OF THE DISCLOSURE         An air damper for an open fireplace is disclosed.          The air damper is used with a heat exchanger which has an electric motor driving a fan to blow air across the top there-of.  In the past the problem has been that heat exchangers of this type become exceedingly hot if the fan does not operate due to a power failure or the like.  However, the present invention overcomes this problem.  The air damper is positioned on the hot air side of a heat exchanger and the device comprises a rotatable metal screen or the like which constitutes a damper capable of assuming a first and a second position.  The damper in the second position prevents the air stream from passing into the distribution passages of the heat exchanger and permits the air stream to pass out into the room where the fireplace is located or into a space safe for high temperatures.  In the second position, the damper permits the air stream to pass into the distribution passages of the heat exchanger and prevents the air stream from passing into the room.  The damper is capable by action of a force to assume the second position when there is a risk of excess temperature in the distribution passages which arises when the function of the fan is disturbed so that the air temperature in the device exceeds a predetermined value.

Abstract: Abstract of the Disclosure Elastomeric materials reinforced with short small diameter insulating glass fibers are disclosed.  The elasto-meric materials may be any of a variety of natural or synthetic rubbers or rubber-like elastomers.  The glass fibers are those commonly designated AAA through B diameters (0.5 to 3.8 microns) and have lengths of from about 3 mm to about 50 mm.  Whereas the large diameter fibers commonly considered to be "reinforcing fibers" have been found not to provide satisfactory reinforcement to elastomers, it has now been unexpectedly discovered that the very small diameter insulating fibers, previously believed not to be satisfactory for reinforcement purposes, do in fact provide excellent rein-forcement to elastomers.  Similarly, it has now been found that short individual fibers, loose or in wool form, can be used for reinforcement instead of the long strands and bundles of continuous glass filaments and woven glass fabrics heretofore relied on by the art.  The reinforcement properties of the short small diameter fibers may be significantly enhanced by the presence of carbon black in the elastomer compound.  The elastomeric materials reinforced in accordance with the present invention, with or without the carbon black component. find use in various heated and moulded rubber products, such as gaskets, tire treads, sheet packings and the like.
